When to prune alexandra palm in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune alexandra palm
Cut dead fronds cleanly at the base with loppers or a saw. The crownshaft sheds spent flower stalks on its own; remove only if they are slow to drop.
Alexandra Palm (Archontophoenix alexandrae) is a self-cleaning palm that drops spent fronds and flower stalks naturally. Pruning is rarely needed — remove only fully dead brown fronds if they do not fall on their own. Never cut green fronds; the crownshaft stays naturally tidy without intervention.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
